Rise in Supplement Use Among Americans: A Study Overview
A recent study published in JAMA Network Open reveals that Americans are increasingly turning to dietary supplements, while the use of multivitamins is on the decline. Conducted by researchers at Memorial Sloan Kettering Cancer Center and the Harvard T.H. Chan School of Public Health, the research analyzed 25 years of data on dietary supplement usage from 1999 to 2023, involving over 63,000 adults aged 20 and older.
Key Findings:
- Overall supplement use has risen from 51% to 60% among U.S. adults, with the most significant increase (from 62% to 78%) observed in adults aged 65 and older.
- The study found that supplement use is more prevalent among women, educated individuals, high-income earners, and those with health insurance.
- Interestingly, multivitamin use has decreased from 35% to 31%, while the intake of individual vitamins such as vitamin D, zinc, and magnesium has surged.
- New and emerging supplements gaining popularity include ashwagandha, elderberry, collagen, and probiotics.
Post-Pandemic Trends:
The surge in supplement interest has been partly attributed to the rise in immune support products such as zinc and vitamin D, especially relevant in the post-pandemic period. This aligns with a broader longevity movement, where consumers are increasingly focused on specific health goals, including immune support and gut health.
Cautions from Experts:
Despite the growing use of supplements, the study indicates no evidence that they are effective for their purported health benefits. Ilana Muhlstein, a registered dietitian, expresses concerns about the reliance on “wellness influencers” instead of healthcare professionals for supplement advice. She emphasizes the importance of a multivitamin as a foundational supplement, especially for those on weight-loss medications like GLP-1, which may reduce nutrient intake.
Recommendations:
Experts suggest:
- Daily Multivitamins: Recommended especially for those on GLP-1 medications to prevent nutrient gaps.
- Smart Choices: Consider a daily probiotic, magnesium, and vitamin D3.
- Elderberry: Suggested as an effective immune booster during cold and flu season.
- Caution: Only take supplements that have undergone third-party testing for quality and safety to avoid potential contaminants.
Conclusion:
As Americans continue to navigate the supplement landscape, it’s crucial to remain informed and cautious, prioritizing evidence-based recommendations from certified nutritionists and healthcare providers over popular trends.
